Gently scrub the sink with a soft bristle brush when cleaning the humidifier. Wipe the atomizer with the soft cloth or cotton swab; shake it a few times after filling the water tank, and then pour it out. If the humidifier will be out of user for a long time, the water in the water tank should be drained; all parts of the humidifier shall be cleaned and dried; then, the humidifier can be stored in a cool and dry place.
